FOCUSING (AUTOFOCUS) Switch the camera to the autofocus mode (AF).Press the shutter button lightly while viewing through the cameras viewfinder,the lens focuses automatically. An in-focus mark will light when lens focuses on the main subject sharply.Press the shutter button further to photograph. *When set on AF mode,be very careful not to hinder the autofocusing move- ments of the lens.Such interference may cause serious damage to the lens mechanism. *Select between the autofocus and manual focus modes by using the AF/MF switch on the camera body when using a Nikon or Minolta lens.The lens for Canon camera has an AF-MF switch on the lens barrel. FOCUSING (MANUAL FOCUS) Switch the camera to manual focusing mode (MF) in case of a Nikon or Minolta. In case of Canon,switch to MF by using AF-MF switch on the lens barrel.Focus by manually rotating the focusing ring while viewing through the cameras viewfinder.The main subject in the viewfinder will be sharp when the lens is focused correctly. * Press the shutter button lightly while operating the lens for focusing.The focus aid mark in the viewfinder will light up when the subject is in critical focus. * At infinity,make sure the image in the viewfinder appears sharp.The infinity position on the lens is made with certain allowances to insure proper focus under a variety of conditions. LENS APERTURE AND AE MODE * Setting lens f-numbers with Canon and Minolta cameras Set the f-number with the aperture setting device of the camera body in accor- dance with the selected photographing mode. * Setting lens f-numbers with Nikon Depending on the photography mode,it is possible to set the aperture on either the lens aperture ring or on the camera body,or both. * Setting aperture on the lens aperture ring Move the lens aperture ring from the smallest aperture,and align it with the mark for the desired aperture. * Setting the aperture on the camera Move the lens aperture ring from the smallest aperture,and set the desired aperture on the camera. FILTER EFFECT CONTROL (FEC) ADAPTER The FEC adapter has been made standard equipment for the A08 and allows a filter to rotate while the hood is attached.By rotating the FEC ring,the filter attached,such as a PL filter,can be adjusted. * The FEC adapter can be attached using the filter screw on the lens.Please note that forcing the screw or tightening too far may strip the threads making it impossible to remove the adapter. * Firmly tighten the FEC adapter when attaching it.If it is not firmly tightened, then it may come off when attaching or removing the hood. *Attaching and Removing the FEC Adapter Attaching 1.Screw the FEC adapter to the hood filter ring in the same way as the filter 2.Rotate the FEC adapter clockwise 3.The FEC adapter attaches to the lens. Removing 1.Turn the FEC adapter counterclockwise 2.The FEC adapter comes away from the lens LENS HOOD *Attaching the lens hood when the FEC is not attached 1.Align the attaching mark on the hood and the hood attaching mark on the lens,then mount the hood evenly. 2.Turn the hood (approx 90 deg.) until the hood attachment mark TAMRON O and the hood attachment mark on the lens lines up and you hear a click when the hood is fixed. * Removing when the FEC adapter is not attached 1.Firmly turn the hood in a counterclockwise direction until you hear a click to release it. 2.Then turn the hood attaching alignment to remove it. * Attaching the lens hood when the FEC adapter is attached 1.Hold the FEC ring firmly with one hand so it does not turn. 2.Line up the hood attaching alignment mark on the hood and the hood attachment mark on the FEC,then mount the hood evenly. 3.Turn the hood until the hood attachment mark TAMRON O and the hood attaching alignment mark on the FEC lines up and you hear a click when the hood is fixed. * Removing the lens hood when the FEC adapter is attached 1.Hold the FEC ring firmly with one hand so that it does not turn. 2.Firmly turn the hood in a counterclockwise direction until you hear a click to release it. 3.Then turn the hood to remove it. * Stowing the lens hood You can reverse and attach the lens hood when it is stowed. 1.Reverse the hood and align the hood attachment mark TAMRON O with the hood attaching alignment mark on the lens and mount it. 2.Rotate the hood clockwise,the hood is difficult to pull off towards the front (because of the construction,the hood will not be fixed when attached backwards.) * The hood for the A08 does not lock when it is reversed due to constructional configuration.When carrying the lens,be sure to hold the lens firmly.If you carry it by the hood portion only,the hood may come off the lens causing it to fall.Do not do this as it may cause bodily harm or substantial damage to the lens. ZOOMING Rotate the zoom ring of the lens while viewing through the cameras viewfinder and compose your image at the chosen focal length. ZOOM LOCK SWITCH Model A08 is equipped with a zoom lock mechanism that prevents the lens bar- rel from extending towards a longer focal length.This mechanism locks the zoom ring in the 200mm position to prevent the lens from extending while hanging. 1.Locking:Set the zoom ring on the lens to the 200mm position.Move the zoom lock switch toward the camera.The lens barrel is locked in position when the portion beneath Lock is red. 2.Releasing:Push the zoom lock switch up.The red indicator is hidden,the zoom lock switch lock is released and the zoom ring can be rotated. * The zoom lock switch cannot be activated unless the lens is set to 200mm position.Do not force the lock switch or try to rotate the lens barrel while locked.Doing so may cause damage to the lens. * The zoom lock mechanism is made to prevent the lens barrel from extending while carried around the neck.When not locked in the 200mm position,the lens may change its focal length during a long time exposure when angled in the low or high position. TRIPOD SOCKET The A08 come equipped with a socket for using a tripod.Firmly fix the lens tri- pod mount to the tripod attaching screw when using a tripod. * Changing the vertical and horizontal position of the camera 1.Turn the tripod socket fixing screw in the counterclockwise direction to loosen it. 2.Rotate the camera using the lens as the axis and line up the indicator on the tripod mount mark using the vertical or horizontal indicators. 3.Tighten the tripod socket fixing screw in a clockwise direction and lock the camera into place. TRIPOD SOCKET (Continued) * Removing the tripod socket 1.Turn the tripod socket fixing screw in the counterclockwise direction and line up the white mark on the top of the knob with the tripod mount mark. 2.Pull the tripod socket fixing screw outward to open the tripod mount ring and then remove the tripod socket. * Attaching the tripod socket 1.Open the tripod mount ring and set it to the lens. 2.Make sure that the white mark on the top of the tripod socket fixing screw and the tripod mount mark are aligned,and then pull the knob outward. 3.Close the tripod mount ring,and tighten the tripod socket fixing screw in a clockwise direction. * Hold the camera firmly when removing the tripod socket so you do not drop the camera or the lens. * Make sure that the white mark on the top of the knob and the indicator on the tripod socket are aligned before you pull on the tripod fixing screw. DEPTH OF FIELD With a camera equipped with a depth of field preview button or a aperture stop down mechanism,the depth of field can be directly observed through the viewfinder screen of your camera. *The optical design for this lens takes into consideration the various features of digital single reflex cameras.However,due to the configuration of the digital single reflex cameras,even when the autofocus accuracy is within specifications, the focal point may be a little forward or behind the optimum point when shooting with autofocus under some conditions. PRECAUTIONS IN SHOOTING * The Tamron lens,SP AF200-500mm (Model A08) employs an internal focusing IF system to achieve a remarkable minimum object distance of 2.5 meters (8.20 feet).Because of the characteristics of this optical design,the angles of view at distances other than infinity are wider than that of the lenses applying an ordinary focusing system. * When the built-in flash on the camera is used,adverse photographic phenom- ena such as corner illumination fall-off or vignetting at the bottom part of the image may be observed.This is due to the inherent illumination of the coverage of the built-in flash,and/or the relative position of the flash to the edge of the lens barrel which causes shadows on image.It is strongly recommended to use a suitable separate flash unit provided by the camera manufacturer for all flash photography. * to attach a lens where the maximum aperture is F3.5 or slower,(ex.High power zoom lenses) is not recommended. * When a teleconverter is attached,the focal length of the lens becomes longer but the depth of field becomes shallower and it may be too difficult to shoot in AF mode.Therefore,focusing in MF mode is recommended when a teleconvert- er is used. * Teleconverters are efficient tools to add focal length to the photographers telephoto lenses including zoom lenses,but cannot be recommended for use with wide angle lenses or zoom lenses that cover wide-angle range focal lengths. * When using the lens in a telephoto focal range,it may be necessary to use a tripod to avoid camera shake.Using high speed film (ISO 400 or faster) with a fast shutter speed is also helpful to reduce the influence of camera shake. * Do not forcibly turn the focusing ring when the lens in set in AF mode.Doing so could damage the lens and/or camera. * Certain camera models may indicate the maximum and minimum aperture values of the lens as approximate numbers.This is inherent to the design if the camera and not an indication of error. * Please be aware that there is no infrared index line on any models listed in this owners manual.Therefore practically no black and white infrared film can be used on this lens. TO ENSURE LONG-TERM SATISFACTION * Avoid touching the glass ele
